By referring again to Figure 3 60 By referring to the drawing it ill b Seen it will be seen that a section of the platen I0 is that there is provided a stand I. Positioned on shown in phantom at Ill-A, this being the this stand I there is a circular base member 2 proper position for a shallow casting. It is obwhich supports a melting pot 3. This melting pot vious that the bars or mat bearers used for a 3 is provided with a heating element 4, preferably shallow casting are necessarily thinner and of electric, and also with a pouring spout 5. Posisubstantially less height than the bars or mat bearers IS. A simple spring catch 23 is provided on one of the shields 9 and is designed to hold the casting box in an upright position. This catch 23 is also used to hold only the top platen H! in an upright position where it will form a shield when the casting box is open, as shown in Figure 2. This catch 23 comprises a tapered piece of spring steel attached to the shield 9 along one edge, thus requiring its manual operation in order to release the casting box from pouring position, or to release the top platen 10 from its shield position.

It Will be seen that the casting box, when released and lowered, will automatically become unlocked due to the resulting sliding action of the platens in relation to each other caused by the engagement of the bolt ends I5 with the pins M of the roller !3.

It will be seen that the height of the casting may be changed by reversing the position of the roller 43, thus moving it closer to the threaded pivots l2, and causing a difference in the space between the platens.

What I claim is:

l. A casting box for casting stereotype plates, said casting box comprising a pair of platens, one of which is pivoted to and positioned between a pair of shields, and the other slidably positioned on a roller which is eccentrically pivoted to and positioned between a pair of shields, catch means for locking said platens together when they are raised vertically, said catch means comprising a plurality of uprights, tapered arms on said uprights adapted to engage the platen opposite, either over the edges of the said platen or through suitable slots in the platen, bars positioned between the said platens to form a suitable casting frame, counter sunk bolts in one of said bars, adapted to hold it securely to the said platen, eccentrically positioned pins formed in the said roller adapted to engage the said counter sunk bolt ends to hold the said platen in position.

2. A casting box for casting stereotype plates, said casting box comprising a pair of platens, one of which is pivoted to and positioned between a pair of shields and the other slidably maintained on a roller which is eccentrically pivoted to and positioned between the said pair of shields, catch means for locking the said platens together when they are moved to vertical position, said catch means comprise a plurality of uprights, tapered arms on each upright adapted to engage the platen opposite, either over the edges of the said platen or through suitable slots in the said platen.
